Description

Technical Field

[0001] This utility model relates to the field of vacuum bottle technology, and in particular to a high-toughness polymer material vacuum bottle based on a single-layer outer casing bottom ultrasonic structure. Background Technology

[0002] A vacuum bottle is a container with a high degree of isolation from the internal and external environments. Its core principle lies in blocking heat conduction, air contact, and microbial growth through a vacuum state. Vacuum bottles can be used in thermos flasks, cosmetic packaging, and food and medicine preservation, among other applications.

[0003] In the prior art, the top of the vacuum bottle used to hold cosmetics is usually covered with a bottle sleeve to seal the pump head and prevent the pump head from contacting the outside air. However, when using it, people often carelessly place the bottle sleeve, which causes the opening of the bottle sleeve to be contaminated. Then, when removing the bottle sleeve, they may accidentally touch the pump head nozzle and cause contamination.

[0004] Therefore, we propose a high-toughness polymer vacuum bottle based on a single-layer outer casing with an ultrasonic structure at the bottom. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where users often carelessly place bottle sleeves, leading to contamination of the bottle sleeve opening and subsequent accidental contact with the pump nozzle when removing the bottle sleeve. The invention proposes a high-toughness polymer material vacuum bottle based on a single-layer outer casing with an ultrasonic structure at the bottom.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-toughness polymer vacuum bottle based on a single-layer outer casing bottom ultrasonic structure includes:

[0008] The bottle body has a slot at the bottom of its inner wall, and a first sealing mechanism is provided in the slot for sealing the bottom of the bottle body.

[0009] A pump head is fixedly provided at the top of the bottle body, and a bottle sleeve is fitted at the top of the bottle body. A through groove is opened on one side of the outer wall of the bottle sleeve. The pump head is located inside the bottle sleeve. A pressing block slides through the top of the bottle sleeve, and a tension spring is fixed between the pressing block and the bottle sleeve.

[0010] A positioning mechanism is provided at the bottom of the pressing block for positioning the pump head;

[0011] The second sealing mechanism is located at the bottom of the pressing block and is used to seal the through groove.

[0012] In one possible design, the first sealing mechanism includes a bottom cover that engages with a slot, an ultrasonic rib fixed to the outer wall of the bottom cover, and a piston fixed to the surface of the bottom cover, the piston being located inside the bottle.

[0013] In one possible design, the positioning mechanism includes two positioning slots and two positioning blocks. The two positioning slots are located on both sides of the top of the pump head, and the two positioning blocks are fixed to the bottom of the pressing block. The positioning blocks and the positioning slots cooperate with each other.

[0014] In one possible design, the second sealing mechanism includes two connecting blocks, both of which are fixed to the bottom of the pressing block. One end of each connecting block is fixed with a connecting cylinder. The inner walls of the two connecting cylinders are slidably connected with sliding rods. A spring is fixed between the sliding rods and the connecting cylinders. The same baffle is fixed between the two sliding rods. The baffle is used to seal the through groove. The four sides of the baffle and the inner wall of the through groove are provided with inclined surfaces.

[0015] In one possible design, both the inner wall of the through groove and the inner wall of the bottle sleeve are provided with sealing grooves, and a first sealing ring and a second sealing ring are respectively fixed in the two sealing grooves.

[0016] In one possible design, a limiting groove is formed on the outer wall of the top of the bottle body, and multiple limiting blocks are fixed on the inner wall of the bottle sleeve, with the limiting blocks and the limiting groove cooperating with each other.

[0017] In this application, during use, the pressing block is pressed directly. The pressing block causes the positioning block to slide along the positioning groove. The pressing block causes the connecting block, slide rod, and baffle to descend. Guided by the inclined plane, the baffle disengages from the through groove, thus exposing the nozzle. At this time, the slide rod extends into the connecting cylinder, and the spring is compressed. Then, the pressing block presses the pump head, causing the cosmetic liquid to atomize and spray out. When the pressing block is released, the tension spring causes the pressing block to reset. The pressing block causes the positioning block, connecting block, connecting cylinder, and slide rod to reset. At this time, the spring recovers its deformation and pushes the slide rod to move. The slide rod causes the baffle to re-enter the through groove and seal the through groove.

[0018] Beneficial effects: In this utility model, the high-toughness polymer material vacuum bottle based on the ultrasonic structure at the bottom of the single-layer outer cover, through the setting of multiple structures such as pressing block, baffle and through groove, allows the user to use the vacuum bottle by simply pressing the pressing block without removing the bottle cover, thus avoiding the problem of contamination of the bottle cover and pump head;

[0019] In this utility model, the high-toughness polymer material vacuum bottle based on the ultrasonic structure at the bottom of the single-layer outer cover can seal the gap between the baffle and the through groove, and seal the gap between the pressing block and the bottle sleeve through the setting of the first sealing ring and the second sealing ring, thereby ensuring the sealing of the bottle sleeve and preventing the pump head from contacting the outside world.

[0020] In this invention, when using the vacuum bottle, the user only needs to press the pressing block, without having to remove the bottle sleeve, thus avoiding the problem of contamination of the bottle sleeve and pump head, while ensuring the sealing of the bottle sleeve and preventing the pump head from contacting the outside world.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figures 1-4 Vacuum bottles, including:

[0028] Bottle 1 is made of high-toughness polymer material (such as PET or PC) to ensure that it is not easily deformed or broken when subjected to external force. The bottom of the inner wall of bottle 1 is provided with a slot 4. The slot 4 is provided with a first sealing mechanism for sealing the bottom of bottle 1. The first sealing mechanism includes a bottom cover 2, which is engaged with the slot 4. The outer wall of the bottom cover 2 is fixed with an ultrasonic rib 6. The bottom cover 2 is tightly connected to the slot 4 of bottle 1 by ultrasonic welding technology. A piston 5 is fixed on the surface of the bottom cover 2. The piston 5 is located inside the bottle 1 to further seal the bottom of bottle 1.

[0029] A pump head 8 is fixedly installed at the top of the bottle body 1 to control the liquid inside the bottle to spray out. A bottle sleeve 3 is fitted at the top of the bottle body 1. A through groove 10 is opened on one side of the outer wall of the bottle sleeve 3. The pump head 8 is located inside the bottle sleeve 3. A pressing block 12 slides through the top of the bottle sleeve 3. The user operates the pump head 8 by pressing the pressing block 12, thereby discharging the liquid inside the bottle. A tension spring 13 is fixed between the pressing block 12 and the bottle sleeve 3 to ensure that the pressing block 12 can quickly return to its original position when no external force is applied.

[0030] The positioning mechanism is located at the bottom of the pressing block 12 and is used to position the pump head 8. The positioning mechanism includes two positioning grooves 9 and two positioning blocks 17. The two positioning grooves 9 are opened on both sides of the top of the pump head 8, and the two positioning blocks 17 are fixed at the bottom of the pressing block 12. The positioning blocks 17 and the positioning grooves 9 cooperate with each other. When the pressing block 12 is pressed down, the positioning blocks 17 cooperate with the positioning grooves 9 to achieve precise positioning of the pump head 8 and prevent the pump head 8 from rotating randomly.

[0031] The second sealing mechanism is located at the bottom of the pressing block 12 and is used to seal the through groove 10. The second sealing mechanism includes two connecting blocks 16, both of which are fixed at the bottom of the pressing block 12. One end of each of the two connecting blocks 16 is fixed with a connecting cylinder 18. The inner walls of the two connecting cylinders 18 are slidably connected with sliding rods 19. A spring 20 is fixed between the sliding rods 19 and the connecting cylinders 18. The same baffle 21 is fixed between the two sliding rods 19. The baffle 21 is used to seal the through groove 10. The four sides of the baffle 21 and the inner wall of the through groove 10 are provided with inclined surfaces. Under the push of the springs 20, the baffle 21 and the through groove 10 can be tightly fitted to achieve a sealing effect. Under the guidance of the inclined surfaces, the baffle 21 can be easily disengaged from the through groove 10.

[0032] This application can be used in the field of vacuum bottles, or in other fields applicable to this application.

[0033] Example 2: An improved high-toughness polymer vacuum bottle based on a single-layer outer casing bottom ultrasonic structure, based on Example 1, is applied to the field of vacuum bottles;

[0034] In another aspect of this embodiment, sealing grooves are provided on the inner wall of the through groove 10 and the inner wall of the bottle sleeve 3. A first sealing ring 11 and a second sealing ring 14 are fixed in the two sealing grooves respectively to enhance the sealing performance of the structure and prevent air from entering the bottle sleeve 3.

[0035] In another aspect of this embodiment, a limiting groove 7 is provided on the outer wall of the top of the bottle body 1, and a plurality of limiting blocks 15 are fixed on the inner wall of the bottle sleeve 3. The limiting blocks 15 and the limiting groove 7 cooperate to allow the bottle sleeve 3 to be fitted on the top of the bottle body 1, which facilitates installation and disassembly.
